To all whom it may concern Be itknown that I, Crmnms H. Lnonnnn, a citizen of the United States of America, residing at Grand Rapids in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Drip-Cups for Refrigerator-Traps; and 1 do hereby declare the following to be a full, clear, and exact description of the inven tion, such as ,yvill enable others skilled. in

the art to which it appertains to make and use the same.

This invention relates to refrigerator construotions and especially to a novel coin struction of drip cup for traps for refrigerators. In a refrigerator the water coming from the ice box is passed through. a drain pipe or conduit'to the outside of the refrigerator and ordinarily a trap is interposed in the length of the conduit for scab ing against the entrance of air into the ice box therethrough. The water from the ice being substantially at a temperature of 32 degrees Fahrenheit cools the surrounding air below the provision box, whereby during humid weather the lower part of the 'conduit collects moisture on the outside or as is commonly known sweats. This is a dis-- advantage in a'refrigerator construction as the collected IILOlStlllQ running down the outside of the conduit comes in contact with the bottom of the refrigerator which being decays the life of the refrigerator less than it would otherwise be. It is the object and purpose'of the present. invention to provide a refrigerator trap with a drip cup in which the cold water'may be carried to the outside of the refrigerator without coming into contact with the lower part of the conduit leading to the outside whereby this part of the conduit is not lowered in temperature and the collection of moisture on the outside does not take place. To attain this end I have embodied my invention in a. construction disclosed in the accompanying drawing in which;

tional view illustrating the drain trap Figure 1 is, a. partial perspectiveand secci drip cup as applied to a refrigerator construction.

be locked in placeon the lining 5.

Like ref erence characters refer to like parts thro; ghout the several views of the drawings.

The refrigerator to which my invention is applied is of the usual character and contains in its construction horizontal partitions 1 and 2, and a bottom 3 .secured together at their rear ends by a back 4. The provision compartment is located between partitions l and 2 said compartment having aliuing 5 of any desired type, preferably of sheet metal coated on its inner side with porcelain. The ice compartment is above the partition 1 and the Water that is given off as the ice melts drains from the ice compartmont through a funnel 6 or the like into a pipe 7 which adjacent its lower end has an enlarged dome shaped member 8 secured thereto formed with an outwardly projecting head 9 around it which-is adapt- .ed to rest against the upper edges of 3. cy-

lindrical member 10 of sheet metal open at its upper end and into which the lower portion of the member 8 inserts. As. the air in the provision compartment is usually dry and of practically the same temperature as the water dropping in pipe 7 no moisture collection occurs on such pipe. Member, 10 has a laterally projecting flange at its-upper end which rests against the lining 5 around an opening cut therein through which member 10 is passed as shown. There is provided in the sides of themember 10, a plurality of screw threads for the reception of an outer member 12 which screws thereon and has a laterally eiitending flange 13-at its upper end adapted to lie beneath the lining 5. it being apparent that by means of this structure. members 10 and 11 may The lower endof the member 10 is reduced in diameter as indicated at 14 and extended through the bottom 3 of the refrigerator..

.VVithin member 10 a drip cup 15 is located which has downwardly and inwardly inclined sides as indicated atlS formin in effect a conical cup fro" the'lower on of which depends a wire or rod17. This wire or rod extends through the extension 14 being located centrally thereof the wire 17 and cup 15.

edges ofthe cup which are adapted to engage with the upper depression in member 10 formed by the screw threads therein. strengthened by The lower end of the pipe 7 below the dome 8 extends into the drip cup tdr a dis tance. WVater entering through pipe 7 fills the cup and, as will be apparent, when the cup is full the lower end of pipe 7 is sealed against the entrance of any air through the pipe into the ide compartment. The overflow of the cup passes down the outside thereof being dammed back by the: upwardly turned ears ,19 from reaching' the outer member 10, and to the wire 17 and thence along the wire to the end from which it maydrop to any suitable drain or recep tacle.

With a construction of the character described, it will be evident that the ice cold water does not come in contact with the member 1-0 or the extension 14 thereof. '1 he air between the partition 2 and bottom 3 according-1y keeps member 10 at substantially an even temperature therewith and no collection of moisture on the outside-of the member 10 from this air can take place. Heretofore the water from the ice box has contacted with said member 10 and any collection of moisture on the outside thereof has been passed to the base'3 which being of wood swells and warps and is much more quickly destroyed than would otherwise be with the base kept in dry condition. The

construction outlined attains thisend by means of very simply and easily manufactured device which may be quickly and easily applied to refrigerator drain pipes and traps.

Various changes in minor detail of structure may be resorted to without departing from the invention. described with .the upwardly and outwardly turned ears for damming back and prevent ing any-of the water getting to the member 10 is a practical and preferred type of construction, it is apparent that various other modified devices may be used to attain the same end so long as the water entering the drip cupis compelled to pass down the out side;thereof and not come into corita'ctwith theinner sides of the member 10. Accordin'gly -I do not wish to be limited to the 'eira ct specific structure disclosed but consider myself entitled to all modifications of struc- 'ft'ure which fall in the scope of the appended claimsdefining the invention.
